It seems to me that most of my friends are the sort of busy, busy people
who always have a half a dozen side-projects which they have the skills
but not the resources to complete.

Today, while chatting with such a friend, he
mentioned something about a project which, if he had a 2-week vacation,
he'd probably be able to get to. After spending a week sleeping, doing
nothing, and puttering around, of course, he'd pick up the project in the
second week. Of course the likelihood that he would have such a vacation
is basically zero, as is the likelihood that the project get done. (Of
course, anything can happen, and some things often do.)

I propose a term. This is a second week project — a project that
only takes place in the second week of a hypothetical mini-sabbatical. I
feel like this could be a useful piece of shorthand for a concept which
would otherwise require a few tedious sentences. Am I right in thinking
that we all have at least a few of these?
